Please note, this only seems to work for whichever desktop environment you are using when you install. If you install in Gnome and then try to run in KDE (or vice-versa) it may not work due to something with Air.

After much Googling and pain and suffering, I finally got TweetDeck working in my 64 bit install of Ubuntu.

If you use Twitter, have more than 20 or so followers and haven't tried TweetDeck yet, you don't know what you're missing out on. TweetDeck will help you organize the people you follow into groups, manage your direct messages, and even set up searches that watch the Twitter stream for certain topics. It's a must-have for anyone using Twitter on a regular basis.

I've used these instructions now in both Ubuntu 8.04 Hardy and 8.10 Ibex, and they worked well.

First, you'll want the getlibs package. (note, link updated 10/8/09)
